pH Down Citric

Earth Pro pH Down Citric is often incorporated into acid formulations. Its function is to prevent the precipitation of gelatinous ferric hydroxide as the acid spends. As a sequestering agent, citric acid can hold as much as 3000 mg/l of ferric iron in spent acid solutions for more than 4 hours at temperatures above 80°C.

Earth Pro pH Down Citric is one of the most economical iron sequestering agents available. However, it should not be used at concentrations greater than 2 kg/m³ as it can precipitate calcium citrate if there is insufficient iron for it to sequester.

As a cementing additive,Earth Pro pH Down Citric can be used as a retarder as well as cement dispersant. It is normally used at between 0.1% and 0.3% by weight of cement.

Earth Pro pH Down Citric can also be used in a wide range of applications where the pH of aqueous fluids has to be lowered.

Mixing & Handling

Although Earth Pro pH Down Citric is of low hazard and toxicity, excess exposure to dust should be avoided to prevent irritation to the eyes, skin and respiratory tract.

As with all organic material, caution is advised when storing or handling near strong oxidizing agents, alkali metals or strong bases.
